*Update to this morning's exciting anecdote:
So the snake dude came. Safely inside, I watched as he inspected behind the storage box. He then shifted the box and reached for the snake. What? He reached with his bare hand. I couldn't believe my eyes. He held the wriggling snake up for me and the kids to see. Then I realized my mistake. No, it wasn't a dreaded rattler. It was only a gopher snake.
In my defense, gopher snakes do shake their tails and are often mistaken for rattlesnakes. Better safe than sorry. The snake dude also told me that he has been retrieving many rattlesnakes from our neighborhood, so yes, it was good to call for help.
